From: Yoann Lopes Date: Mon, 1 Oct 2012 15:50:55 +0000 (+0200) Subject: Use QVideoGraphicsItem in the videographicsitem example. X-Git-Tag: upstream/5.2.95+rc1~181 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b616dd5165a2f1e554eda1f85acf6c6000ba24b9;p=platform%2Fupstream%2Fqtmultimedia.git Use QVideoGraphicsItem in the videographicsitem example. The videographicsitem example now uses QVideoGraphicsItem instead of a custom QAbstractVideoSurface. The old code has been moved to a new example: "customvideosurface/customvideoitem".
